So Michael and I got a hole in the schedules to record Episode #3 last night.
I had some new toys (mixer, better mic, and whatnot) so I hope it shows on this episode.
Show Notes:
so last night Michael and I did our first podcast…. it went ok but there were a few hiccups…. so I’ve read alot of what works and what doesn’t so i figured i’d write up what i’m currently using and the changes i make as i go along.
Current setup:
System - I had a macmini doing nothing so figured i’d put it to use - 1.6 Ghz CoreDuo with 2 gigs ram and a 120 gig HD should be more than enough to get the job done.
Mic - I’m currently using a basic PC headphone at the moment - The Plantronics 470 . While it won’t win any awards for comfort it seems to be an OK mic.
Software - We are using Skype to bring Michael’s audio in and after playing around with various packages i chose UberCaster to record, post, and render the podcast.
Performance and Recording Results:
Welp some of the issues I ran into were…
#1 - my mic placement wasn’t the greatest and the recorded sound wasn’t as good as i was hearing through my system… i’ve already ordered a new “PC” mic replacement (The Sennheiser PC166 for when i’m on the road) as well as a Studio mic setup (I’ve got an old Shure condenser mic as well as i just ordered a Sennheiser HMD 280 setup).
#2 - For whatever reason Ubercaster kept crapping out on skype around 20-25 minutes into each recorded session. This left segments where I was talking and couldn’t hear Michael or vice-versa. To fix this and to also get a better mic setup, I’ll likely just use my firewire enabled mixer and record the skype session on its own in garageband then bring it into Ubercaster for post work and rendering. Will be an extra step but would give me more flexibility.
Post Production - actually went well, Ubercaster’s interface is really easy to work with and compared to garageband or Adobe’s Audition i found it really easy to clean up sections, add filters where needed, and repair the broken skype sessions.
Lessons Learned:
So i was surfing some of the blogs the other day and came across Michaels Farnum’s first podcast and figured” what the hell” and see if he wanted to team up and see how things worked out.
We recorded our first show last night ……
Some show notes:
Stick with us as we get all the bugs worked out. I hope to bring some new perspectives and liveliness to security podcasting.
So a co-worker wanted my eeepc 900 after a little bit of back and forth on price, I sold it to him and bought the new 1000h series EEEPC. I like the HD and new processor. However as most have noted the Hardware is different, and to make the laptop run Backtrack 3 requires a bit of changes:
#1 - X doesn’t start by default, to remedy this - at boot up select the VESA mode … If you are running from SD card and want to keep your save changes options.. modify your startup to look like this:
/etc/sysconfig/sysconfig.cfg -
LABLE eeepc
MENU LABEL BT3 VESA with Persistent Changes
KERNEL /boot/vmlinuz
APPEND vga=0×317 initrd=/boot/initrd.gz ramdisk_size=6666 root=/dev/ram0 rw changes=/dev/sdb2 autoexec=kdm
That will fix the boot up issues and set you down the right path…
#2 - the Ethernet card isn’t supported with the native BT3 drivers so you’ll need to go grab them and compile…
Download Linux driver from ASUS (card is Atheros(R) AR8121/AR8113 PCI-E):
http://support.asus.com/download/download.aspx?product=1&SLanguage=us-en&type=map&model=P5KPL-CM
(click the Drivers tab and set your OS to LINUX)
Copy the drivers to a USB drive and put them onto your BT3 system, unrar the files in the zip file, then start the compile fun:
Cd to the src directory (WHEREEVER/LinuxDrivers/L1e_Lan/l1e-l2e-linux-v1.0.0.4/src)
make
make install
A file called atl1e.ko is made, that’s your driver - Make install doesn’t work properly so its up to you to move the file.
Move to: /lib/modules/2.6.21.5/kernel/drivers/net/at1le.ko
insmod ./atl1e.ko
ifconfig -a should list your ETH0 card now.
#3 - The native wifi card isn’t supported for injection and monitor mode yet. My simple fix for this was to simply replace the card with one that is supported… namely the AR5008 based Gigabyte Aircrusier N300. Works with darn near everything. The native card is easily accessible through the bottom of the case under the same expansion cover you have to remove to install more ram (the RAM / HD / and Wifi card are all in this area).
I also did my little external antenna mod between the USB and Ethernet ports like on the 900 but i’ll tell you its really a tight squeeze to make it fit inside the case.
